Replace array of objects












-1














I have below array of objects



const array = [
{ home1: "05:45", dayOfWeek: 1, away: "09:30"},
{ home1: "05:15", dayOfWeek: 2, away: "09:30"},
{ home1: "17:30", dayOfWeek: 5, away: "09:30"},
{ home1: "16:30", dayOfWeek: 7, away: "09:30"}
]


I have four dayOfWeek (1,2,5,7). Now I need to push the remaining three (3,4,6) with the dummy object ({ home1: "05:30", dayOfWeek: 7, away: "09:30"})



Now the logical part is I don't know which dayOfWeek are present in the array. There may be only one, two, three or blank. I need to push 7 days in that array every time.



How this can be done? Please suggest me the best way



Thank you!!!

  • you can loop through current array and store daysOfWeek in an array then loop the other 7 days dummy array and check if its in the previous array then do not need to insert that days. hopes you get that

One option would be to make a Set of the days contained in the array so far, then iterate from 1 to 7, pushing a new object to the array with that day if it's not contained in the set:






const array = [
{ home1: "05:45", dayOfWeek: 1, away: "09:30"},
{ home1: "05:15", dayOfWeek: 2, away: "09:30"},
{ home1: "17:30", dayOfWeek: 5, away: "09:30"},
{ home1: "16:30", dayOfWeek: 7, away: "09:30"}
];
const dummy = { home1: "05:30", away: "09:30" };
const days = new Set(array.map(({ dayOfWeek }) => dayOfWeek));
for (let i = 1; i <= 7; i++) {
if (!days.has(i)) array.push({ ...dummy, dayOfWeek: i });
}
console.log(array);





I used a Set to reduce complexity, but I suppose if you only ever need 7 objects, it doesn't matter much, you could use find instead without creating a collection beforehand






const array = [
{ home1: "05:45", dayOfWeek: 1, away: "09:30"},
{ home1: "05:15", dayOfWeek: 2, away: "09:30"},
{ home1: "17:30", dayOfWeek: 5, away: "09:30"},
{ home1: "16:30", dayOfWeek: 7, away: "09:30"}
];
const dummy = { home1: "05:30", away: "09:30" };
for (let i = 1; i <= 7; i++) {
if (!array.find(({ dayOfWeek }) => dayOfWeek === i)) {
array.push({ ...dummy, dayOfWeek: i });
}
}
console.log(array);

    Use Array.reduce to create a set of existing days. Now iterate and check whether there is an entry in set, if not push the object in array.






    const array = [
    { home1: "05:45", dayOfWeek: 1, away: "09:30"},
    { home1: "05:15", dayOfWeek: 2, away: "09:30"},
    { home1: "17:30", dayOfWeek: 5, away: "09:30"},
    { home1: "16:30", dayOfWeek: 7, away: "09:30"}
    ];
    let daysSet = array.reduce((a,c) => a.add(c.dayOfWeek), new Set());
    let obj = { home1: "16:30", dayOfWeek: 7, away: "09:30"};
    for(let i = 1; i <=7; i++) {
    if(!daysSet.has(i)) array.push(Object.assign({}, obj, {dayOfWeek:i}));
    }
    console.log(array);

    You can use "Array.from" and loop 7 times like below.






    const array = [
    { home1: "05:45", dayOfWeek: 1, away: "09:30"},
    { home1: "05:15", dayOfWeek: 2, away: "09:30"},
    { home1: "17:30", dayOfWeek: 5, away: "09:30"},
    { home1: "16:30", dayOfWeek: 7, away: "09:30"}
    ]

    // sort array by day of week. Ignore this step if you are sure it will be sorted always
    array.sort((a,b) => a.dayOfWeek - b.dayOfWeek)

    var result = Array.from({ length: 7}
    , (_,i) => array[0].dayOfWeek == i + 1
    ? array.shift()
    : { home1: "05:30", dayOfWeek: i + 1, away: "09:30"})

    console.log(result)

      You can first get all the dayOfWeek present in a array with map(). Then use for loop to insert the dayOfWeek by checking whether that is present in the array or not.



      You can try the following way:






      const array = [
      { home1: "05:45", dayOfWeek: 1, away: "09:30"},
      { home1: "05:15", dayOfWeek: 2, away: "09:30"},
      { home1: "17:30", dayOfWeek: 5, away: "09:30"},
      { home1: "16:30", dayOfWeek: 7, away: "09:30"}
      ]
      let exist = array.map(d => d.dayOfWeek);

      for(let i = 1; i<=7; i++){
      let dummy = { home1: "05:30", dayOfWeek: 7, away: "09:30"};
      dummy.dayOfWeek = i;
      if(!exist.includes(i))
      array.splice(i-1, 0, dummy);
      }
      console.log(array);

              Use Array.reduce to create a set of existing days. Now iterate and check whether there is an entry in set, if not push the object in array.

              { home1: "16:30", dayOfWeek: 7, away: "09:30"}

              You can use "Array.from" and loop 7 times like below.






              const array = [
              { home1: "05:45", dayOfWeek: 1, away: "09:30"},
              { home1: "05:15", dayOfWeek: 2, away: "09:30"},
              { home1: "17:30", dayOfWeek: 5, away: "09:30"},
              { home1: "16:30", dayOfWeek: 7, away: "09:30"}
              ]

              // sort array by day of week. Ignore this step if you are sure it will be sorted always
              array.sort((a,b) => a.dayOfWeek - b.dayOfWeek)

              var result = Array.from({ length: 7}
              , (_,i) => array[0].dayOfWeek == i + 1
              ? array.shift()
              : { home1: "05:30", dayOfWeek: i + 1, away: "09:30"})

              console.log(result)

                      You can first get all the dayOfWeek present in a array with map(). Then use for loop to insert the dayOfWeek by checking whether that is present in the array or not.



                      You can try the following way:






                      const array = [
                      { home1: "05:45", dayOfWeek: 1, away: "09:30"},
                      { home1: "05:15", dayOfWeek: 2, away: "09:30"},
                      { home1: "17:30", dayOfWeek: 5, away: "09:30"},
                      { home1: "16:30", dayOfWeek: 7, away: "09:30"}
                      ]
                      let exist = array.map(d => d.dayOfWeek);

                      for(let i = 1; i<=7; i++){
                      let dummy = { home1: "05:30", dayOfWeek: 7, away: "09:30"};
                      dummy.dayOfWeek = i;
                      if(!exist.includes(i))
                      array.splice(i-1, 0, dummy);
                      }
                      console.log(array);
